Question

Which of the following is relevant with respect to a group of whales, seals and sharks?

• A. Seasonal migration
• B. Thick subcutaneous fat
• C. Convergent evolution
• D. Homeothermy

Answer 1

The correct option is C Convergent evolution

Whales (mammals), seals (mammals) and sharks (fishes) inhabit similar habitats, and have developed similar morphological features that make them look similar in certain ways, and are also functionally similar. This is termed as adaptive convergence or convergent evolution. Though mammals and pisces are distantly related groups with different origins, these organisms have got adapted to similar environments.
